The supersaturation is an essential parameter to control industrial batch crysta llization processes. Until now a quantitative online measurement of supersaturat ion was not possible. A new sensor system consist-ing of an interdigitated capac itor (IDC) and a surface acoustic wave transducer is mounted on top of a peltier element, which allows a thermal cycling around the crystallization temperature. Together with a multivariate signal evaluation the online measurement of the su persaturation could be demonstrated.
